Yuhang Li

I am a Ph.D. candidate in Electrical and Computer Engineering at the University of California, Los Angeles (UCLA), working in the Bio- and Nano-photonics Lab under the mentorship of Prof. Aydogan Ozcan. Before joining UCLA, I received my B.Eng. in Optical Science and Engineering from Zhejiang University in 2021.

My research focuses on computational imaging and optical neural networks. I design diffractive optical processors that compute with light — performing tasks such as quantitative phase imaging, imaging through random diffusers, universal polarization transformations, and nonlinear information processing, all at the speed of light propagation. More recently, I have been exploring optical generative models and model-free training of optical processors using reinforcement learning.

My work has been published in journals including Nature, Science, Light: Science & Applications, Advanced Photonics, Nature Communications, and Science Advances, and has been cited over 1,300 times (h-index: 18).
